Abstract
Nasopharyngeal carcinoma (NPC) is a malignant disease that exists in Asia, the development of imaging techniques and radiation therapy in the last 5 years has utilized 75% of diagnoses as nasopharyngeal carcinoma without metastases. The development of radiotherapy techniques has changed from conventional 2-dimensional (2D) to 3-dimensional conformal radiotherapy (3DCRT) and intensity modulated radiotherapy (IMRT). IMRT technique is one of the newest treatments at this time, so this technique requires a high level of precision and specific requirements either in immobilization or dose distribution, so that the accuracy rate for random or random systems is better than conventional 2D and 3D-CRT techniques. This study uses a descriptive qualitative method with a literature review study approach by collecting and analyzing data that aims to determine the role of the IMRT technique in external radiotherapy on the dose value of OAR for nasopharyngeal carcinoma. Based on the literature that forms the basis for the assessment, several advantages of the intensity modulated technique are shown. IMRT radiotherapy is capable of producing highly conformal doses with complex dose gradients, as well as being able to increase dose distribution within the target volume and reduce OAR doses.
